Vodafone have applied to erect a 13.4m mobile phone mast at Mauldeth Road/Didsbury Road, SK4 3JL. The searchable planning database isn't accessible at time of writing, but more information should be available searching for DC021801 on the searchable planning database or see the plans at Heatons Library, Thornfield Rd, Heaton Moor.
For information on the impact of phone masts, the SCRAM website is a good starting place.
